f dam/44v??? a Patented Sept. 28, 1937 UNITED STi PA'i'E'l' FFIQE 2 Claims.

This invention relates to dual window construction, particularly adapted for use in frame buildings, wherein spaced studding is used in the Walls thereof; the principal object being to provide a simple window unit for installation within the walls of such a structure.

Another object is to provide such a unit for a double sash window, wherein the uppermost sash is greater in length than the lower sash to provide for selective adjustment of same in accomplishing either a closed or an open window condition, as desired.

Other objects and advantages of the invention Will appear in the following description thereof.

Referring now to the accompanying drawings, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a plan view of my improved dual window as it would appear from the inside of the building with the top window down and the screen in place.

Figure 2 is a vertical central section of Fig. 1.

Figure 3 is a broken perspective view of my improved window and frame therefor.

Figure 4 is a somewhat enlarged perspective view of the completely assembled unit ready for installation within a building.

A double sash window having the above referred to selectivity is old in the art as disclosed in my Patent No. 1,502,142, dated July 22, 1924, so that the instant invention refers only to the novel form of frame structure therefor.

In the drawings, l and 2 rep-resent spaced studs in an ordinary wall of a wooden building, 3 the outside sheathing; and 4 the lath and 5 the plaster of the inside finish of the wall. 6 represents the window sill, l the side members of the window frame, and 8 the upper rail of the window frame, 9 the inside finish or trim, I0 the lower sash, H the upper sash, while i2 is the outside top rail of the window trim, and 24 the outer side trim member of the frame.

The elongated double length upper sash H is illustrated as having a central rail is, below which it is glazed as at M and above which it is provided with wire screen as at l5. In the preferred embodiment of the invention it is desirable that the entire window installation should be in a completely assembled unit, as illustrated in Fig. 4 and to which end, the window frame is fully assembled, with the upper portion of the sash ll completely housed in when in the position illustrated. This housing comprises the relatively thin wooden covering I6 which is attached at its sides to the upright members or jambs H, which are reduced continuations of the side members I of the window frame, while the outer covering of this housing portion is represented at l9, and corresponds in thickness to the ordinary inch sheathing boards illustrated at 3, which latter are nailed directly to the studding of the wall, as is of course the covering 19. For convenience of illustration of the unit, this auxiliary sheathing or covering 89 projects all around the entire side and upper portion of the window unit as well as inwardly on both sides of the window opening where it forms the outer blind stop for the upper sash, so that when an opening is prepared for same intermediate of the studding in the wall of a building by properly spacing the lower transverse member 20, and the uppermost transverse member 2 I, all that is necessary is to place the completely assembled unit (excepting the inner trim) into said opening and fasten it there. In this event, however, the transverse member 22, corresponding to those described at 2B and 2 I, is set on its edge in order to make room for the housing of the upper portion of the window unit, and either one or more uprights 23, as the case may require, may extend from the cross member 2! to the cross member 22, thus providing a substantial structure within the wall above the lower portion of the window frame.

It is thought the advantages of such a unit of window installation are obvious, as well as the convenience provided in having a window in which a screen is at all times constantly available.

The principal difiiculty in providing for a unit of this kind is that the upper transverse rail, placed intermediate of the side studding for the two sash window, must be placed on edge and flush with the inner face of the studding, instead of on its side, as is common. This then provides room behind the upper transverse rail for the installation of my improved dual window unit.

From the above it is apparent that with my improved dual window installation, the upper light of the window may be changed from glass to screen at will, and in this novel construction wherein the outer facing of the pocket in the unit is made to project from three sides thereof to abut with the outer sheathing of the building, the outer side trim members of the unit are made to overlap and cover such abutting joint, thus insuring a weather tight union wholly about the installation.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

l. A completely pre-assembled double sash window unit for installation Within the wall of a building, including in combination a Window frame having side jambs, top rail, sill, said side jambs extending upwardly and being reduced in width above said top rail, and said top rail also being reduced in width, and inner and an outer covering for the reduced portions of the side jambs thereby providing a pocket above the top rail having a bottom opening into the window frame, said outer covering projecting beyond the side jambs and top rail and downwardly upon either side of the outer edge of said side jambs and forming the outer blind stop for the uppermost sash of said Window, a single light and a double light window sash slidable within said frame, and the upper portion of said double light window being slidable within said pocket when desired.

2. A pre-assembled double sashed pocket window and frame therefor having side jambs, top rail, and sill, an inner covering member for said pocket, an outer covering member for said pocket secured to and extending beyond the side jambs and top rail, said outerwardly projecting portion being for cooperative alignment with the sheathing of a wall to which the window and frame may be applied, and said outer covering member acting as the outer blind stop for the upper sash of the window.
